11.4 A Comparison of Methods
11.1 Introduction
The IEEE Standard Dictionary of Electrical and Electronics Terms defines frequency response in stable, linear systems to be “the frequency-dependent relation in both gain and phase difference between steady-state sinu- soidal inputs[r]

Hydrogenerators. The hydrogenerator is a low-speed (100 to 360 rpm) salient-pole machine with a vertical shaft. A typical number of poles is from 20 to 72. They are mounted on a pole spider, which is a welded, spoked wheel. The spider is mounted on the forged steel shaft. The[r]

K in Eq. (48.9) is called the electromechanical coupling constant.
48.4 One-Dimensional Propagation
If an acoustic plane wave as in Eq. (48.2) propagating within one medium strikes an interface with another medium, there will be reflection and transmission, much as in the correspo[r]

Rule 1. All impedances may be multiplied by any constant without affecting the transfer voltage ratio. Rule 2. To modify the cut-off frequency, divide all inductors and capacitors by the ratio of the desired frequency
to the normalized frequency.

To read the stored information optically, the Kerr effect is used to detect the presence of these very small magnetic domains within the MO layer. When a low-power polarized laser beam is reflected by the perpen- dicularly oriented MO medium, the pola[r]

For ease of operation and convenience in wiring the GIS back to the substation control room, a local

UCA is a standards-based approach to utility data communications that provides for wide-scale integration from the utility enterprise level (as well as between utilities) down to the customer interface, including distribution, transmission, power plant, control center, and cor[r]

This arrangement allows various operating options as additional lines are added to the arrangement; loading on the system can be shifted by connecting lines to only one bus.
A double bus, double breaker scheme is a high-cost arrangement, since each line has two breakers and requires[r]

18.2 History
The gas-insulated transmission line (GIL) was invented in 1974 to connect the electrical generator of a hydro pump storage plant in Schluchsee, Germany. Figure 18.1 shows the tunnel in the mountain with the 400-kV overhead line. The GIL went i[r]

While a number of processes can be used for coating superabrasives (for example[r]

Leakage Reactance
When the practical transformer is considered, additional concepts must be introduced. For example, the flow of load current in the windings results in high magnetic fields around the windings. These fields are termed leakage flux fields. The ter[r]

A look at each of these criteria will enable the user to get a better under- standing of the requirements.
The two factors, which most affect high turbine efficiencies, are pressure ratios and temperature. The axia[r]
